You are right...However, here the configuration send_100_continue_response
is introduced to keep compatible with some old origin server (e.g. HTTP 1.0
server). When it's enabled, ATS would send back 100 continue response to tell
the client to go ahead, in case the origin server does not know the header and
do nothing with it.
